Antimicrobial fabrics have become essential in organizing and managing infestation and reducing odor formation by microbes. Various green sources add antimicrobial properties to fabrics, especially cotton. However, the major problem with microbial fabrics is the reduction of antimicrobial activity after each wash. Cupressaceae pods have shown natural potential as an antimicrobial agent in herbal medicine. This study utilizes cupressaceae for incorporating antimicrobial properties in cotton fabric. After the methanolic extraction of the cupressaceae extract, it was applied to the cotton fabric. The application of the extract to cotton fabric was made by optimizing concentration, temperature, and pH parameters. The extract modified cotton showed the best performance at 15 wt.% of concentration, 140°C and pH 7.5. The treated fabrics were tested in the presence and absence of the binder using the standard washing method ISO 105-C10:2006. Mordant-treated fabric retained 16.4% more activity after 20 washes. Finally, the antimicrobial activity of the greenly developed antimicrobial cotton fabrics was checked against Staphylococcus, E. coli, Bacillus, and C. albicans by using AATCC 100-2004 test method. The study indicated that the prepared cotton fabric showed better antimicrobial activity against the earlier mentioned strains, except for C. albicans. The prepared antimicrobial fabric showed a wide range of antimicrobial activity and less fungal activity. Thus, the prepared fabric can be used for wound dressings, hospital staff gown material, and athlete's sportswear to prevent microbial infection.
: The deformation behavior and mechanical properties based on the aluminum-lithium alloys (FMLs) was investigated to optimize the manufacturing process and further interface interaction. The primary structures of the FML composites were made with two sets of plies. From there, six secondary composites with different fibre sheet orientations were made. Then, interlaminar tensile, flexural, and peeling properties of FMLs were tested. The fiber orientation role in the case of failure behaviors of FMLs under different conditions was also revealed. The results have indicated that the plies design significantly enhanced the interlaminar properties of the FMLs and orientation of fiber laying has significantly affected the flexural strength. The peeling test has shown higher fiber-to-metal interfacial bonding with the value of ≥ 80 N/m2 over metal-to-metal adhesion. The plies increase the mechanical properties of composite based at fiber orientation and thickness, but too much impairs performance. The 3/2 plies showed a value of ≤ 385 MPa which has better results in axial structure analysis as compared to over 4/2 composite layers. The peak values appeared under different parameters like adhesive bonding and parallel fiber orientation represented in the qualitative analysis section. The surface microscopy of aluminum-lithium alloy sheet and cross-section failure morphology of composite has been done at a different sighting. Surface characterization, fiber orientation breakdown and deformation morphology have been studied with respect to alloys' elongated grains and micro pits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
